KRATON® POLYMERS THERMOPLASTIC RUBBER-G-7705 (SEBS) | ||
KRATON® G7705 THERMOPLASTIC RUBBER (SEBS) (Styrene Ethylene Butylene Styrene Block Copolymer) | ||
Shell Elastomers - Kraton® Polymers Thermoplastic Rubber-G-7705 | ||
Kraton® G polymers based on SEBS (styrene ethylene butylene styrene) may be added to plastics and rubber-based products for applications including handlebar grips, toothbrushes, and sports mouth guards and car components. Strength and elasticity are improved and resistance to oxidation provided. The compounds can be overmoulded to the surface of hard plastics components to improve grip or appearance. Thermoplastic Elastomers combine the processing advantages of plastics with the rubber-like performance of Elastomers. Known as two-phase systems, these copolymers are comprised of both hard (plastic) and soft (elastomeric) molecular regions, with each region contributing advantages and limitations to the final material performance. Chemically, fully cured thermoset rubber particles are dispersed throughout a continuous thermoplastic matrix. | ||
APPLICATIONS | ||
Kraton®
has a broad range of applications that spans from bumpers to bellows,
vibrational dampers, couplers, and grommets. Also used throughout the automotive, major and small appliances, and aerospace industries. |
